Specification of Letters Patent.

Patented Nov. 23, 1915.

Application filed October 28, 1912. Seria No. 728,275.

To all whom it may concern: Be it known that I, ALFRED C. STEWART, a citizen of the United States, residing at Los Angeles, in the county of Los Angeles and State of California, have invented a new and useful Controlling Device, of which the following is a specification.

This invention relates to a device which is particularly intended for controlling a valve, for example, the auxiliary air valve for a carbureter of an automobile engine, such as disclosed in my Patent No. 1,035,651, dated August 18th, 1912,and the main object of the invention is to providea controlling device which can be placed in convenient position for operationand which will be adapted for' operation of the valve through the agency of the flexible mechanical connection. e g

Another object of the invention to provide improved meansfor securing the controlling'device in position.

Other objects of the invention will appear hereinafter.

v The accompanying embodiment of the invention, and referring thereto:

Figure 1 is a side elevation of the controlshowing the connection thereof with the valve. Fig. 2. is a side elevation of the controlling device. Fig. 3 is a section on line cc a2 in Fig. 2. Fig. 4 is a plan of the controlling device.

The controlling device comprises a base or frame 1, with a lever 2 pivoted to said base, anelasticrod or wire 3 connected to said for inclosing and guidsaid casing bein supported at one end on the base 1 %n order to enable the casing 4 to adjust itself automatically to the elastic member 3 and thereby minimize thefriction involved in the operation of said member, said casing is preferably supported on the base 1 by means of a swivel-post 5, mounted to turn on the base 1 by pivotal, connection 6 and provided with a transverse bore 7 to receive the end of easing 4, said casing being secured in said bore by means of a set screw 19. One end of the-elastic member 3 is secured to the lever 2 by means of a fasteningdrawings illustrate an screw 8, the other end of said elastic'memher being connected to Y operate the valve 10, the casing 1 being secured to the casing of said valve Said valve 10 is shown in connection wlth the intake pipe 11 for an internal combustion engine to control the supply of auxiliary air to said intake pipe.

cavity or recess 12, adapted to fit against one side of said postor support, and a clamp formed as a U-shaped member 13 of round Wire, of malleable metal, is pivoted or hinged at 14. to the base 1,-the end portions 15 of the arms of said U-shaped member being screw threaded, as shown at 16, and adapted to pass through openings 17 in the base 1. These arms are sufiiciently flexible to enable them to be bent around the post or support, and when they have been bent in this manner they are passed through said openings 17 and drawn tight by nuts 18 screwing thereon and engaging frame 1 so as to clamp the controlling device firmly on the post or support. By this means the controlling device may be fitted to posts of different sizes. Whatever may be the position of the support 20, the pivotal connection of the swivel-post 5, with the frame 1, enables the casing 4 to adjust itself to position of least strain, and of least friction on the operating member 3.

' What I claim is:

1. A controlling device for valves comprising a flexible operating member, a frame, a lever pivoted on said frame, a swivel post pivoted on said frame, a flexible tubular casing for said operating member, means to detachably secure the casing to the post, and means to detachablyand adjustably secure the flexible operating member to the lever whereby said operating member may be taken up or let out.

2. In a controlling device for valves, the combination with a curved support, of a substantially flat frame having an offset concaved portion to engage the curved support, a lever pivoted on the frame, valve operating means connected with the lever,

'a .U-shaped inember piv ted on the fr aI ne set my, hand at Los Angeles California this and having bendable arms embracing the 11th day of October 1912 support said frame having ope'ningsfex- 1 tending therethrough and" receiving said L RE STEWART? 5 arms, and. means to secure saiderms to the In presence offrame. 7 Y ARTHUR P.
